6.2 Apply to register a sender ID for an ABN entity

As a certified telco, there are 2 options for applying to register a sender ID for an ABN entity.

• Option 1 − apply on behalf of the ABN entity as a participating telco – section 11 of the Standard applies. Follow the instructions in 6.2.1
• Option 2 − apply on behalf of the ABN entity as a certified telco – section 12 of the Standard applies. Follow the instructions in 6.2.2

This means that prior to commencing the application, you must establish which option the entity prefers. You may wish to note that if it elects to be treated a non-ABN entity:

• its participation is not reliant on its ABR records being up to date and including current/accessible contacts (depending on the mechanism/s a certified telco uses to verify an entity and its authorised representatives)
• its employees that do not have Australian identity documents (for example, an Australian driver licence or passport) can represent the entity for the purposes of the register through a certified telco (for example, where an entity with an ABN has offices and staff offshore).

To apply to register a sender ID for an ABN entity (Option 1): 

1. Click on the Sender IDs tab.
2. Click on the Apply to register a Sender ID button. 

You will be taken to the Application to register a sender ID form.
